ECOPICS_Mx_Water infiltration of the soils from Pico de Orizaba Protected Park.

ECOPICS Project : In situ Infiltration tests Field campaign June 2018 by Beatriz Marin-Castro, Eduardo Hernández Hernández Last modification : February 2019 by Beatriz E. Marín-Castro The value of Kfs was calculated according to the method of Wu2 (Wu et al., 1999), using a quasi-steady infiltration rate in a single ring infiltrometer (Fig. 1). Each plot has an unique name made of : Altitudinal band : from 3400 to 4400 --------------------------------------------------------------------------------------------------------------------------------------------------- SWC0 and SWCf are mean soil water content before and after the infiltration test, made with a TDR Kfs is the mean hydraulic conductivity (cm/h) Ksat is the laboratory saturated hydraulic conductivity -------------------------------------------------------------------------------------------------------------------------------------------- For more information about the method : Wu, L., Pan, L., Mitchell, J., & Sanden, B.

ECOPICS项目：2018年6月原位入渗试验野外作业，由Beatriz Marin-Castro与Eduardo Hernández Hernández开展；最终修订于2019年2月，由Beatriz E. Marín-Castro完成。
饱和导水率（saturated hydraulic conductivity, Kfs）的计算依据Wu2法（Wu等，1999），采用单环入渗仪（single ring infiltrometer）测得的准稳定入渗速率（图1）。每个样地均拥有唯一命名，其命名由海拔带构成：3400至4400。
---------------------------------------------------------------------------------------------------------------------------------------------------
SWC0与SWCf分别为入渗试验前后的土壤平均含水量，采用时域反射仪（TDR, Time Domain Reflectometry）测定；Kfs为平均饱和导水率（单位：cm/h）；Ksat为实验室测定的饱和导水率。
